IUCN status: Vulnerable
EPBC Predator Threat Rating: Very high
IUCN claim: “Recent research has demonstrated marked detrimental impact of introduced predators: Red Fox (Vulpes vulpes) and feral Domestic Cats (Felis catus)”
Plains rats remains were found in the foxes’ diet (Pavey et al. 2008; Pavey et al. 2014). Read & Cunningham (2010) described an occasion where more plains rats were captured inside than outside a fenced reserve where carnivores were excluded (no data or analysis was provided). Rats were last confirmed in Koonchera Dune, SA, 18.5-28.5 years after foxes arrived (Current submission).
Rats were last confirmed in Mootwingee National Park, NSW, 72.5-37.5 years before foxes arrived (Current submission).
There are no studies evidencing a negative association between foxes
and plains rats which report data. In one region the extirpation record
pre-dates the fox arrival record.
Current submission (2023) Scant evidence that introduced predators cause extinctions.
